    <td><p>You may edit the viewability, the name, the elevation and the heights of a level by double-clicking
      on its tab, or by choosing <i>Plan &gt; Modify level</i>... from the menu.<br>
      The modification pane of a level lets you edit its attributes, but  shows also a table 
      describing all the levels of a home where the selected line matches the currently edited level.</p>
<p align="center"><img src="images/editingLevels.png" alt="Modify level"></p>
	    <p>The thickness of the floor is used to compute the vertical border around a floor in the 3D view. This surface is visible  around holes in the floor and at the border of a mezzanine or a balcony.<br>
	      The elevation 
	    of a level can be positive or negative. In the later case, the ground will be automatically dug in the 3D view each time a piece of furniture, a room or a closed set of walls is added to the underground level. This feature can be used to place a swimming pool in the ground or to create a basement with one or more levels.</p></td>

              		at the right of the table to change the order of appearance of the edited level. Changing the elevation and/or 
       		  the order of appearance of a level will automatically update the order of the tabs.</td>
